DATA SOURCES
The new econometric analysis undertaken by InterVISTAS Consulting used three different datasets:
• US Department of Transport database 1B (DB1B). DB1B provides data on the US domestic aviation market. Traffic figures reflect the actual number of passengers on a particular route, while average price reflects the estimated average one-way travel price paid (in USD).
• IATA’s Passenger Intelligence Service (PaxIS) database. This database captures market data through IATA’s Billing and Settlement Plan (BSP). It provides traffic and travel price estimates for airport- pair routes around the world (e.g. JFK-LHR, CDG- FRA). However, data is only available from 2005 onwards.
• UK International Passenger Survey (IPS). The IPS is a survey of passengers entering or leaving the UK by air, sea or the Channel Tunnel. This report exclusively used outbound to Western Europe leisure air passenger traffic data from the IPS. Traffic figures reflect the estimated number of passengers on a particular airport-pair route, while average travel price reflects the estimated average price paid (in GBP).
